As more information becomes available, CDC’s travel notices
will be updated.

Travelers to areas with cases of Zika virus infection
are at risk of being infected with the Zika virus. Mosquitoes that
spread Zika are aggressive daytime biters. They also bite at night.
There is no vaccine or medicine for Zika virus. The best way to avoid
Zika virus infection is to prevent mosquito bites.

Some travelers to areas with Zika will become infected while
traveling but will not become sick until they return home and they might
not have any symptoms. To help stop the spread of Zika, travelers
should use insect repellent for three weeks after travel to prevent
mosquito bites.

Some people who are infected do not have any symptoms. People who do
have symptoms have reported fever, rash, joint pain, and red eyes. The
sickness is usually mild with symptoms that last from several days to a
week. Severe disease requiring hospitalization is uncommon and the
number of deaths is low. Travelers to areas with Zika should monitor for
symptoms or sickness upon return. If they become sick, they should tell their healthcare professional when and where they have traveled.

CDC has received reports of Zika virus being spread by sexual contact
with sick returning travelers. Until more is known, CDC continues to
recommend that pregnant women and women trying to become pregnant take
the following precautions.

Guillain-Barré syndrome (GBS) is very likely triggered by Zika in a
small proportion of infections, much as it is after a variety of other
infections. CDC is working with Brazil to study the possibility of a
link between Zika and GBS. For more information on Zika, visit www.cdc.gov/zika.
